Sanity check. Single Exchange 2010 server to HA 2013 upgrade
Hi all.
Could some of you fine experts please sanity check my thinking here? I have an all-roles Exchange 2010 server with 2000 mailboxes and want to move to a Exchange 2013 two server HA set up. I want to avoid making any Outlook client side changes. Does this list make sense?
1. Setup new server with all roles, Exchange 2013.
2. Create CAS Array on Exchange 2013 box with just itself as member.
3. Move all mailboxes to new server, client's Outlook will go to new CAS Array.
3. Install hardware NLB with same FQDN as current Outlook profile and point to Exchange 2013 box and install on network. Users notice no change.
4. Remove Exchange 2010 box from network and reinstall as Exchange 2013.
5. Add new 2013 box to CAS Array.
6. Create DAG to include both 2013 servers
7. Update NLB to point at both 2013 servers
Many thanks.
Paul.

All your references to the CAS Array are wrong - there is no CAS Array in Exchange 2013
I agree with Simon. See the below link where it states so.

You need to carefully plan the migration, as it requires many important configurations . So as stated by Simon, getting a professional consultation is very much important since you have 2000 mailboxes.

Thanks Simon good advice as always.
1 - OK
2 - OK
3 - create DAG and add server itself to DAG.
4 - Install hardware NLB with same FQDN as current Outlook profile and point to Exchange 2013 box and install on network.
5 - create new DB.
6 - move a few mailboxes and test all the setup.
7- after tests are done and are working as expected move all users.
8 - make sure you move address book generation to 2013 server.
9 - Remove Exchange 2010 box from network and reinstall as Exchange 2013.
10 - Add new 2013 box to CAS Array.
11 - Add server to DAG to include both 2013 servers
12 - Update NLB to point at both 2013 servers
I believe there are still some pieces that are missing from the big picture, but it depends of your environment.
Good luck.
